User-Definable Application Sensing Tunnel
You may define special applications that require multiple connections such
as Internet gaming, video conferencing, and Internet telephony. The BLW-
04EX will then sense the application type and open a multi-port tunnel for
it.

Security
Th e BLW-04EX supports s ecurity feat ures t hat deny Int ernet access t o

Compatible with all popular Internet applications
Many advanced applications are provided by the BLW-04EX, such as:
LAN Access
The BLW-04EX provides connectivity to 10/100 Mbps devices, making it
easy to create a network in small offices or homes.
Internet Access
This devi ce s upports Internet access through a DSL or cabl e connect ion.
Since many DSL providers us e PPPoE to est abli sh communicat ions wi th
end users, t he BLW-04EX incl udes a buil t-i n cl ient fo r t his proto col ,
eliminating the need to install this service on your computer.
Shared IP Address
The BLW-04EX shares a single IP address with up to 253 users. Using only
one ISP account, multiple users on your network can simultaneously browse
the Internet.
Virtual Server
If you have a static IP address, you can set up the BLW-04EX to act as a
virtual host for network address t ranslat ion. Rem ote users acces s various
services at your site using the static IP address. Then, depending on the
requested service (or port number), the BLW-04EX routes the request to the
appropriat e server (at an int ernal network IP address). This secures your
